• A. $\frac{9}{29}$
• B. $\frac{11}{32}$
• C. $\frac{9}{17}$
• D. $\frac{18}{31}$

Answer 1

The correct option is C $\frac{9}{17}$

As per table books sold on Monday, Wednesday and Friday on shop no $3$ are $15,12$ and $10$

And as per table books sold on Monday, Wednesday and Friday on shop no $3$ are $12,14$ and $9$

And total bookssold on Monday, Wednesday and Friday on all shops is $48,49,39$

Then total books sold on Monday, Wednesday and Friday on all shop $3$ $=15+12+10=37$

Then total books sold on Monday, Wednesday and Friday on all shop $4$ $=12+14+9=35$

And total books sold on Monday ,Wednesday and Friday on all shop $3+$ shop $4$ $=48+49+39=136$

Then fraction of books sold on Monday, Wednesday and Friday $=$ $\frac{37+35}{136}=\frac{72}{136}=\frac{9}{17}$
